Does Acid Reflux Dry Out Your Throat? Hidden Symptoms of Reflux Esophagitis

Modern medicine diagnoses this condition as laryngopharyngeal reflux. While typical reflux esophagitis is marked mainly by digestive symptoms such as heartburn and sour regurgitation, laryngopharyngeal reflux is distinguished by throat and larynx symptoms so prominent that it is often called silent reflux. It develops because gastric acid or stomach contents reflux past the esophagus into the laryngopharynx, causing direct damage to the mucosa. The laryngopharynx is far more vulnerable to acidic substances than the esophagus. Although the esophageal mucosa has defenses to endure strong acid to some extent, the laryngopharyngeal mucosa is easily damaged and inflamed by even minimal amounts of gastric acid. This inflammation dries out the mucosa, impairs mucus secretion around the vocal cords, and can cause vocal cord edema, leading to hoarseness, chronic cough, a foreign body sensation in throat, and throat dryness. This explains why acid reflux occurs more readily when lying down at night, leaving the throat dry and the voice hoarse upon waking in the morning. Furthermore, if gastric acid enters the airway, it can cause bronchospasm and provoke a cough. Neurologically, acid reflux can stimulate the vagus nerve to trigger the cough reflex, or hypersensitize the sensory nerves of the laryngopharynx, worsening discomfort. In essence, the concept of stomach fire flaring upward in Donguibogam corresponds directly with the modern medical explanation of inflammation of the laryngopharynx caused by acid reflux. It is important to remember that this is not merely a throat problem; stomach health is directly connected to throat health.
